The latest course of planting techniques and methods of root celery

Celery is a kind of celery whose main edible part is its root. Celery can be used not only for eating, but also for juicing. It has the effect of lowering blood pressure, diuresis, improving appetite, etc., and the fragrance of ordinary celery is light, and the crude fiber content is very low. It is very suitable for the elderly to eat, so how should root celery be grown? The following small series brings you the planting technology of root celery. Let's take a look together!

1, planting time

The planting time of root celery is mainly in spring and autumn. In spring, it is cultivated in greenhouse from February to March, and then transplanted at the end of April. Under normal management, it can be harvested in August. Or planting at the end of April, and then the next time around November. Because the root of root celery is more suitable to live in a humid environment, it grows healthily and yields higher in the process of planting and in a warmer environment. If the summer temperature is too high, it is only suitable for planting in autumn.

2. Sowing seedlings

The pericarp of root celery is hard, contains more oil, and has poor water absorption ability, so its germination ability is weak, its seedling quality is poor, and its germination rate is low. Therefore, seedling is very important, in order to do a good job of seed germination before sowing, water temperature control at about 25 degrees, soaking for about 9 hours. Then wash the seeds, air dry, mix well with the soil and spread evenly over the seedbed. Seedbed soil should be fine and broken soil, apply enough fertilizer after watering through water. Ensure that the seeds are in full contact with the soil, and then control the temperature at about 20 degrees Celsius to strengthen management and promote seed germination.

3. Timely planting

Before planting, soft, deep and fertile plots should be selected as planting fields, and then garden cleaning should be done well, the land should be deeply ploughed and proper amount of base fertilizer should be applied. After controlling the planting density, transplant properly. When digging seedlings, be careful not to hurt the roots of root celery. Because the recovery ability of root celery is poor, it will affect the growth ability after injury, cause various diseases and insect pests, lead to poor growth of root celery, and lead to death in serious cases. Therefore, when digging seedlings, try to transplant with soil, not only to ensure that the roots will not be damaged, but also to continue to provide nutrition for the root celery during the transplanting process.

4. Field management

The growth of root celery is more like water, but when watering, it is not allowed to flood irrigation. It is necessary to increase the frequency of watering and reduce the amount of watering each time. In the leaf growth peak period, to the ground is not dry do not water for the principle. In the fleshy root expansion period, sufficient water should be ensured, and then appropriate topdressing should be applied. The fertilizer should be mainly phosphorus and potassium fertilizer, which can effectively promote the fleshy root expansion of root celery. Then do a good job of intertillage and weeding, prevent the hollow phenomenon of root celery, timely pick leaves, improve field permeability, avoid consuming too much nutrition, and affect the growth of plants.

The above is a brief introduction to the root celery planting technology. The growth ability of root celery is relatively strong, and it is relatively simple when planting. However, attention should also be paid to pest control to prevent fatal damage to root celery. Today's introduction is here, this article is for reference only, thank you for reading and support.
